She is relentless

"A promise is a promise," she said with an evil smile.

Her hand slid down my body, squeezes my cock for a minute before passing over my balls and then working its way to my ass.

"No, Amy, I am not into-"

Before I can finish she jams her finger into my asshole. If you have never felt that, its hard to explain. It hurts the first time, but there is also some pleasure to it. I continued to protest as she finger banged me, but despite that, my tired cock began to rise to attention again.

"Amy, please, I...don't...do...ohmygod..."

She expertly worked my asshole over, and after a few minutes I could feel the next load of cum building up. At last all i could do was moan. As I neared climax, once again my vision darkened, and I thought i was going to black out.

When I came, once again I felt it through my whole body, which tensed against the handcuffs. It was the second most intense orgasm of my life...and all I could muster was a tiny little glob of cum.

"The things we are finding out tonight," she said. "You have swallowed your own cum AND you like it in the ass."

I felt dirty. I felt used. Most of all I felt violated.

"Now you get your reward for being a good boy," Amy told me.
